The present invention provides a lifting motor belonging to the field of automation, especially relates to a small-scale high-torque horizontal rotation lifting motor. The upper end cap of the liftingmotor, the side wall of the lifting motor, a support separator and a lower end cap of the lifting motor are connected in order to form a cavity, a servo driver, a rotation nut, a lifting screw, a rotor and a rotor connection piece are arranged in the cavity, a rotor connection piece is rotationally connected with the upper end cap of the lifting motor and the support separator, and the rotor is connected with the outer surface of the rotation connection piece and is rotated driven by the servo driver; the rotation nut is inserted in the rotor connection piece and is linked with the rotor connection piece, the lifting screw is arranged in the rotation nut and is in threaded connection with the rotation nut; the servo driver drives the rotor, and the rotor connection piece and the rotationnut are rotated to achieve lifting motion of the lifting screw. The small-scale high-torque horizontal rotation lifting motor achieves the small size and the high torque of the horizontal rotation lifting motor and meets the requirements of the automatic application device on the electrical apparatus elements.
